Application filed December 23, 1814. Serial No. 878,736.

To all whom it may concern.

Be it known that I, Gnonen RICHARD SCHUELER, a citizen of the UnitedStates, at present residing at 4C Pendrill street, Beverley Road,Kingston-upon-Hull, England, have invented certain new and usefullinprovements in Presses; and i do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention has for its object an i1nproved machine or apparatus forexpressing oil, juice or fluid from seeds, nuts, fruit, fish andmaterials and substances generally which contain oil, juice or fluid,and which is also adapted to produce shaped blocks or pieces fromplastic materials or substances and the like. p

In order that my invention may be readily understood and carried intoeiiect, I have appended hereunto six sheets of explanatory drawings onwhich Figure 1 is a side view of apparatus in accordance with myinvention for expressing oil or fluid from oil or fluid containing .materials or substances and for forming the residuum into compressedlengths or pieces, the near bearings for the shafts of the twocompressing wheels being omitted, Fig. 2 is a front view of same, andFig. 3 is a plan view with the feed spout removed. Fig. 1 is a sideviewof a portion of each of the compressing wheel s, Fig. 5 is a sectionthrough one of such wheels, and Fig. 6 is a similar section through aportion of a wheel showing a. slightly modified shape of bottom or innerwall of the space between each two teeth, Fig. 7 is a front view of oneof the frames which carry the cheekpieces for inclosing the meshingpoint of the compressing wheels, and also shows the same provided withbuilt up passages to form an extracting box, with a die-plate, and withmeans for regulating the size of the holes or passages through thedie-plate, Fig. 8 is a side view of Fig. 7 Fig. 9 is a section througha. portion of Fig. 8, Fig. 10 is a front view and Fig. 11 a side view ofone of the series of plates used in the building up of the extractingbox, Fig. 12 is a front view of the cover plate which keeps the bushesin the die plate in position, Fig. 13 is a side view of same, Fig. 14 isfront view of one of the bushes, and Fig.

15 is a plan view of same. Figs. l to 15 inclusive are drawn to a largerscale than Figs. 1, 2 and 3.

In constructing a machine or apparatus in accordance with my invention,and as illus trated in the appended drawings, I employ a. pair, or aplurality of pairsvof suitable toothed wheels, one pair only of suchwheels, 1 and 2 being shown in the machine or apparatus illustrated,said pair of wheels being somounted in relation to each other, the oneon a shaft 3 and the other on a shaft 4 rotatable in suitable bearings 5carried by suitable uprights or standards 6, that as they rotate, theirteeth 7, 8 mesh at the point of engagement of the two wheels, the teeth7 of the wheel 1 filling, or almost filling the spaces 9 between theteeth 8 of the wheel 2, p

shape, in that, in place of being fiat it is of angle or like shape incross-section as shown more clearly at Figs. 5 and 6, thereby to providetwo inclined or curved surfaces 11, 12 whereby the material fed to saidspaces is caused to be delivered at each side of the wheel, and the rootof each tooth of the wheels is reduced from the point where it joins theangle or like shaped bottom or inner wall of the space, to form awedgeshapedpocket 13, as shown more clearly at Fig. l, in which pocketsthe material compressed in the spaces between the teeth rests or is helduntil such time as it is required to be expelled. I

Situated at each side of the compressing wheels 1 and 2, or of each twowheels, if a plurality of pairs of wheels are employed, is a suitableplate, which plates I will call cheek plates said'cheek-pl'ates 14, 15being each fitted in or detachably secured to a frame whereby each canbe removed when worn, to allow of a new one being substituted, theframes 16, 17 with the cheek-plates 14, 15 being so fitted as to inclosethe meshing point of the wheels 1 and 2 and to project to a suitabledistance above such point to insure the materialfed to the wheels to becompressed, falling between the two wheels, whereby it is caused toenter the spaces between the teeth of the two wheels in known manner, asthe wheels rotate. Each cheek plate has suitably shaped apertures in itat the points which correspond with the position of the wedge shapedpockets of the wheels 1 and 2 where the teeth of the said two wheelsare, in engagement, the material acted on by the teeth of the wheels inthe spaces of the respective wheels passing through these apertures whenexpelled from the wedge shaped pockets of the wheels.

Fitted, according to one mode, at each side of the pair of compressingWheels 1 and 2, or of eachpair of wheels, if a plurality of pairs ofwheels are employed, are extracting boxes or devices of any suitablekind, into WhlCll extracting boxes the material when expelled from thepockets in. the wheels 1 and 2 into the apertures in the cheek-plates-14, 15 passes, said extracting boxes having, accordingto a: preferredmode, the same number of passages as there are apertures in a checkplate, one type of'extracting box being illustrated in longitudinalsection at Fig. 9. Each extracting box consists of a number of plates 18one of which is shown in front view at Fig. 10 and in side view at Fig.11, each of which plates has a plurality of holes 19 through it, thenumber of holes preferably correspondingwith. the number of holes in thecheek plate uprto which the ex racting box fits. The holes 19 in any oneplate are all preferably of the. same size but are slightly differentin: size to those in adjoining" plates: whereby when the plates areplaced face to face as shown in Fig. 9, the

passages. formed by the holes inthe several plates increase: in sizeinthe direction in which the material is caused to travel through theextracting box or device, with the result that the material as it passesthrough the passages expands. gradually or step by step, which expansionhas the, effect of preventing the formation of a skin around thematerial, or should onev chance to form, of breaking it up, therebyallowing of the oil .orthe like fluid in the material escaping freely.

The plates 18 are thickened on one side at the points, where the holesare situated, to form boss-like portions 20- around the holes, finegrooves. being made in the face of each boss-like portion for theexpressed oil or liquid to escape through.

The plates to, form one extracting box, are arranged as beforedescribed, in a recess or chamber 21 provided for the purpose in theframe 16', and the plates to form the other extracting box are arrangedin :1

similar chamber in the other frame 17, the side walls of the saidchambers forming the side walls of the extracting boxes.

A passage 22 is provided in the frames for the oil. or liquid expelledfrom the material in the extracting boxes to escape through.

At the front of each frame, according to the arrangement shown, isfitted a die-plate 23 which has holes or passages 24 through it, in eachof which holes is fitted a bush 25, shown removed at Figs. 1 and 15.bush is provided with a hinged or pivoted door or portion "26 adapted tobe turned on its pivot 27 to control the size of the passage through thebush, each door when closed or. partially closed forming the re sistanceagainst which the material traveling through the passages in theextracting box and die-plate, is pressed. A plate 28 is secured in frontof the die-plate to keep the bushes in position in the holes in thedieplate, said plate having recesses 29 in its sides at the points wherethe holes in the die-plate are situated, to allow the compressedmaterial to exude through the dieplate.

ltfleans of any suitable kind may be employed for adjustingsimultaneously all the hinged doors of the bushes in the passages in thedie-plate, one and a convenient arrangement which I describe by way ofexample only, cousisting in providing holes each tapped with ascrewthread, in the ends of the die-plates, each hole running through toa passage in which a bush is situated, and in turning into each hole thescrew-threaded end of a spindle.

In the accompanying drawings, each extracting box is shown as having sixpassages arranged in two series of three each, consequently there aretwo series of bushes, three in each series, and twoseries of threespindles, three of such spindles 30, 31 and 32 being turned into theright hand end, and the other three 33, 3d and 35 turned into the lefthand end of the die plate 23., The center spindle of each series has adifferent.

direction ofscrew-thread to that on the spindle above and below it. Eachspindle is provided. with a pinion or like toothed wheel, each marked36, the pinion or like wheel on the center spindle of each seriesmeshing with the pinion or like wheel on the spindle above and below.The. plain outerends. of the series of spindles 30, 31, 32 are supportedin bearings in; a plate 37, and the corresponding ends of the spindles33, 34, 35 are supported in hearings in a similar plate 38.

On the outer end of the center spindle 31 is mounted a spur or liketoothed wheel 39 which meshes with a pinion or like wheel 40 on a shaft4-1, and on the spindle 34- is mounted a spur or like wheel 4-2 whichits meshes with a second pinion or like wheel 48 on said shaft 41,whichshaft41 is provided with a hand wheel 44, or other suitable meansto enable it to be rotated. By

rotating the shaft 41 in the required direc-' tion, the several spindlesare rotated simultaneously, the screw-threaded end of each being thusturned into its hole in the dieplate and acts on the door of a bush andpresses it inward, the several doors being acted on simultaneously andall moved to exactly the same extent;

Driving of the compressing wheels 1 and 2 may be effected by anysuitable means, the means shown in the accompanying drawings consistingin loosely mounting on the shaft of the wheel 2, a bush 45 on which arekeyed a pulley 46 and a pinion wheel 47 the pinion gearing with a spurwheel 48 keyed on the shaft of the compressing wheel 1. The pinion wheel47 drives the spur wheel 48 which in turn drives the compressing wheel1, which compressing wheel drives the compressing wheel 2 by gearingtherewith.

The material or the like to be compressed is preferably fed to thecompressing wheels in regulated quantities by any means suitable for thepurpose, but preferably through a feed spout in which is located asuitable helix or portion or portions of a worm screw 49 indicating thefeed spout, 50the helix or the like, 51 the spindle on which the helixor the like is mounted, one means of driving the spindle 51 consistingof a belt 52 driven by a pulley 53 mounted on a vertical spindle 54provided with a disk 55 which rims infrictional contact with one" sideof the gear wheel 48, the driving of the feed controller thus beingregulated by the rotation of the spur wheel and the compressing wheels.

The mode of operation of the machine or apparatus illustrated, is asfollows:The material to be compressed isfed into the feed spout 49 andfalls on to the helix or the like 50 therein which cuts through it thussevering as it were a given portion at each rotation, the severedportion falling between the compressing wheels 1 and 2 and into thespaces between the teeth of each wheel at the point where the teeth arecommencing to mesh. The teeth of each wheel compress the material in thespaces of its fellow wheel during the meshing period, the material as itis being compressed being divided into two portions by the angle or likeshaped back or inner wall of the space, said two portions being forcedinto the wedge shaped pockets 13 at each side of the wheel in whichpockets the two compressed portions of material are held during onerevolution of the wheel, such portions being expelled by the portionsnext formed, each two portions formed in a space expelling the twoportions last formed in the spaces in both wheels simultaneously andbeing expelled from both wheels in the manner described. As eachcompressed portionof material is expelled from a pocket, it

passes through one of the apertures in the 1 cheek plate situated atthat side of the wheel, consequent on such aperture being so situatedthat the pocket in which such portion is held comes during its rotation,into line with such aperture and the compressed portion is at that timeforced into such aperture by the portion of material being compressed atthe time.

In the arrangement shown, compressed portions of material are expelledpractically simultaneously from three pockets at each side of eachwheel, six passing into an extracting box at one side of the pair ofwheels and six into a similar extracting box at the opposite side of thewheels, the material being subjected to furthercompression in theextracting boxes caused by the continuous feed of material by thecompressing wheels, which compression expresses the oil or liq' uid outof the material, such oil or liquid flowing down the faces of the plates18 provided with holes 19 which form the gradually enlarging passages,and out through the passage 22 provided for the purpose, the residuumpassing out through theholes in the die-plate in the form of lengths orpieces of compressed material.

In cases wherethe machine or apparatus is to be employed for producingshaped blocks or pieces, from plastic or like materials or substances,and the expressing of oil or the like is not a part of the process,

suitable dies are substituted for the extracting boxes or the like, theplates which go to form the hopper or like device being so formed, ifdesired, as to effect the purpose of die-plates.

When a plurality of compressing wheels are employed, the machine frameand the wheel shafts 3 and 4 are extended, and the additional pair orpairs of wheels are mounted on the said shafts in relation to each otheras described with reference to the compressing wheels 1 and'2, the otherparts of the apparatus being duplicated as will be readily understood.

If desired, one only of the compressing wheels of the pair or of eachpair may be provided with space bottom or inner walls and pockets formedas before described and illustrated in the accompanying drawings, theother wheel of the pair, or of each pair having flat space bottoms orinner walls and the usual type of tooth root.
